The scientific poster is the primary format for communicating the findings of the Unit 4 Area of Study 3 investigation. A poster must summarise a complete scientific investigation clearly and concisely, using both text and visual elements, for a general scientific audience.
A scientific poster:
- Communicates the key elements of an investigation in a visually accessible format
- Is designed to be read by someone who was not involved in the investigation
- Allows viewers to quickly grasp the question, approach and key findings
- Supports further discussion — a poster at a conference invites questions and dialogue
A VCAA Environmental Science poster should include:
| Section | Content |
|---|---|
| Title | Specific, descriptive; includes the key research question or finding |
| Introduction/Background | Relevant context; scientific concepts; why the investigation matters |
| Aim and Hypothesis | Clear aim statement; testable, specific hypothesis |
| Materials and Methods | Summary of methodology, key procedures and equipment; sufficient for reproducibility |
| Results | Data tables, graphs, calculated statistics; factual description of patterns |
| Discussion | Interpretation of results; link to hypothesis; explanation of patterns |
| Conclusion | Direct answer to the research question; supported by evidence |
| Limitations | Sources of error and uncertainty; how they affect conclusions |
| Acknowledgements | Credit to individuals who assisted (supervisors, landowners, laboratory staff) |
| References | Full citation list of all sources consulted |
A poster must communicate all of the above without the space of a full written report. Succinctness requires:
| Instead of: | Write: |
|---|---|
| ‘The data collected during the investigation showed that…’ | ‘Results showed…’ |
| ‘It can be seen from the graph that there is an increase in…’ | ‘SID increased with vegetation cover…’ |
| ‘As can be clearly seen in Figure 1…’ | ‘Figure 1 shows…’ |
| Principle | Application |
|---|---|
| Hierarchy | Most important elements (title, key result) largest and most prominent |
| White space | Don’t crowd elements — space makes posters readable |
| Consistent style | One font family; limited colour palette; consistent graph style |
| Flow | Reading order logical (left-to-right; top-to-bottom) |
| Figures dominant | Show data in graphs; leave prose for interpretation |
The acknowledgements section:
- Credits individuals who provided assistance but are not listed as an investigator
- Should include: supervising teacher; field assistants; landowners who allowed access; laboratory staff
- Does not include authors of cited papers (these belong in the reference list)
- Brief and professional in tone
Example acknowledgement: “The author thanks [Teacher name] for guidance in investigation design, and [Landowner name] for allowing access to field sites. Laboratory analysis was assisted by [Name] at [School].”
All sources used must be listed in the reference section, including:
- Published scientific papers and reports
- Books and textbooks
- Government and organisation websites
- VCAA study design (if cited)
APA (American Psychological Association):
- Journal article: Author, A. A. (Year). Title of article. Journal Name, Volume(Issue), pages. DOI
- Website: Author, A. A. (Year). Title of page. Organization. URL
Scientific journal style (Vancouver):
- Author A, Author B. Title. Journal. Year;Volume:pages.
VCAA accepts either style as long as it is consistent.
Every factual claim sourced from another publication must have an in-text citation:
- APA: (Author, Year) → ‘Declining bee populations threaten pollination services (Klein et al., 2007)’
- Vancouver: [1] → ‘Declining bee populations threaten pollination services [1]’
VCAA school-assessed posters are evaluated on:
- Scientific accuracy of content
- Quality of investigation design and execution (reflected in poster)
- Clarity and succinctness of communication
- Appropriate use of scientific conventions (terminology, referencing)
- Evidence of critical thinking (discussion of limitations, uncertainty)
STUDY HINT: Before designing your poster layout, sketch a rough structure showing where each section will go. Allocate space proportionally to the importance of each section — results and discussion typically warrant more space than materials and methods. Avoid the common mistake of spending too much space on background and too little on results interpretation.
